Application led June 3, 1924. Serial No. 717,519.

to a class ot' articles for use in the toilet oi persons.

My invention has for its object primarily to provide an article ofmanufacture adapted to be made in the forms ot brushes de signed to beemployed by persons for shaving, cleaning the teeth and the like, andwhich is of a construction whereby the bristles will be covered fromexposure when not in use to prevent the collection of dust and liabilityof contamination by impurities as well as enabling the brush to besafely packed tor avoiding the danger oli beingr damaged whentransported. The invention consists essentially of a brush having anexteriorly threaded bristle head, and surrounding the head and bristlesis a tubular protective shell having a threaded end removably screwed onthe head. The other end ot the protective shell may be closed by a capwhich is detachable to permit the shell to be removed and readjusted onthe head whenV it is desired to use the brush.

Another object of the invention is to provide on the head a handlehavingr a chamber with its entrance at the 'tree end of the handle topermit powder or paste to be car* ried in the handle, and in theentrance may be a removable intersticed cap or sievingr member forallowing powder in the chamber to be distributedtherefrom.

A. further object of the invention is toV provide a brush ot a simple,efficient and durable construction which may be made in appropriatesizes and designs.

With these and other objects in view, the invention will be hereinaftermore fully described with reference to the accompanying drawing formingra part ot this specification in which similar characters of referenceindicate corresponding parts in all the views, and will then be pointedout in the claims at the end of the description.

In the drawing, Figure 1 is a detail sectional view taken through oneform of my improved brush showing the parts thereof in closed positionswhen not in use.

llig. 2 is a sectional view, partly in elevation, taken through thebrush with the parts thereof in adjusted positions for using the brush.

Fin/'ure 3 is a sectional view, partly in elevation, taken through adiierent form of brush with the parts thereof in closed positions.

Fig. a is a view looking at the brush from the free end of its chamberedhandle.

5 is a sectional view taken on the line 5 5 o1 Fig. 1, and

Fig. 6 is a sectional view, partly in elevation, taken on the line 6-6of Fig. 1.

The brush has a head 10 which is preferably ot al shape having acylindrical wall 11, and on one end oit' the head is mounted .thebristles 12 of the brush. When the brush is oi. a form for use bypersons for shaving purposesthe bristles are disposed from the head inthe manner common to brushes of this class, as shown in Fig. 1, and whenthe brush is made of a form for cleaning' teeth the bristles 12 aremounted on a back, as 13, Fig'. 3, which extends from one end of thehead. The end part of the cylindrical wall 11ot' the head opposite tothe bristles 12 is threaded, at 14, and eX- tending from this threadedend ot the head 10 is a handle 15. The handle 15 may be hollow toprovide a chamber 16 with its entrance 17 at the tree end of the handle.The handle may be ot any appropriate shape and size so that the chamberwill be adapted to hold a quantity of tace or tooth powder, as 18, ortor holding a tube ot suitable tooth paste, as 19. The handle is of adiameter preferably smaller than the diameter of the head l() to providean annular stop shoulder, as 20, Vadjacent the threads 14. The innertace of the wall oit' the chamber 16 at its entrance 17 may be threaded.at 21, and in this entrance is a removable sieving member or cap 22.

The sieving member or cap 22 is prefer ably of a form having,r acircular plate 23 of a larger diameter than the diameter of the handle,and protruding from one face of this plate is an exteriorly threadedannular flange 24 which is screwed in the threaded entrance 21 ot thechamber 16 of the handle so that the plate 23 ot the cap abuts upon theend of the wall of the entrance. The diameter ot' the plate 23 of thesieving cap 22 being larger than the diameter of the handle the edge ofthe plate provides an annular flange, as 25, extending beyond theexterior of the handle. The flange ot the plate is also of a diameterapproximately similar to the diameter ot the stop shoulder 20 ot thehead 10 ot the brush, Through the central part of the plate 23 of thecap 22 are spaced holes or peritorations 26 which lead through the plate23 ot this cap into the chamber 16 ot the handleto provid-e outlets fordistribu tionol the contents ot' the chamber when in form ot' powder. Onthe outer tace ot the plate is pivot/ed. at 27. the central part of arotative dislr 28 ot a size so that it covers the pertorations 26 ot theplate 23 ot the sieving cap, and in this disk are a number of spacedholes or pertorations 29 adapted to register with the pertorations 26 otthe plate when the disk is rotatively adjusted accordingly. Thepertorations ot the plate 23 `and the perforations of the dislr arerelatively arranged, that when the disk is rotated also -a givendistance the spaces between its pertorations lwill close theperforatio'ns ot the 'plate 23 to prevent passage ot the contents of thechamber 16.

When the brush is not 'inuse the bristles 12 are vcovered by a shell orcap, asr30. This -cap is preferably ot a form having a tubular member'or annular wall 31 ot acircumterence so that it closely tits removablyon the cylindrical wall 11 ot the head 10 ot the brush` and this tubularmember is longer than the combined lengths ot' the head 10 and thebristles 12 of the brush. One end portion otthe tubular member 31encircles the wall otV the head, and part oit' this end portion of themember is interiorly threaded. asl at 32. rThe threaded part A32 ot thetubular member is screwed on the threads let/ot the head 10 ct thebrush, and on the end of the tubular member 3l adjacent the threads isaninwardly protruding an nular flange 33 which surrounds the handle 1 5and abu'ts against the stop shoulder 20 of the head. The e;\*ter.ioi'1ot` the tubular member 31 at the flange 33 and at the threads 32 is alsothreaded, at 34. The eX- terior ot the end of the tubular member 31opposite the ilange 33 is threaded, at 35, and on these threads isscrewed the inte riorlj'7 threaded flange 36 of a4 cap 37 which normallycloses 'the tubular member at the tree ends of the bristles l2.

The shell or cap 3() is removably applied to the brush by detaching thecap 37 Y from the tubular member 31, and uns'crevving the sieving cap 22from the chambered handle l5. The tubular member 31 is then moved overthe handle by passing the handle through the threaded end 35 of thetubular member so that the flange 33 of the member abuts against thestop shoulder 2O of the head. The cap 37 is then screwed on the threadedend 35 of the member 3l, and the ed bristle head7 a bristles ot thebrush will be inclosed from exposure to the `collection ot' dust orimpurities ot the air. The sieving cap 22 is afterward rescrewed in theentrance of the chamber 16 ot the handle. lVhen it is desired to use thebrush, the cap 37 is removed .troni the tubular member 3l, and thetubular member is slidably moved on the handle 1? so that the liange 33abuts against the Harige 25 ol the sieving cap 22. The threaded end part35 ot' the tuluilar member 31 of the protective shell or cap30 will thenbe disposed en the bristle head1() ot the brush. aud when the cap 37 isscrewed on lthe threads 34 ot the tubular member the flange 35 ot thesieving cap 22 will be clamped between the flange 33 ot the tubularmember and the cap 37 ot this member. The bristles 12 ot the brushwillthereby be exposed tor using the brush.

ln the toregoing` description, I have embodied the preferred lormof myinvention, butl I do not wish to be understood as limiting myselfthereto, as l am aware that modi iications may be made therein withoutdeparting'ifrom the principle or sacrilicing any ot the advantages otthis invention, therefore. I reserve to myself the right t0 make suchchanges as fairly fall within the scope thereof.
